Barney is almost always seen in Moe's Tavern, where he is a regular. His desperation for alcohol has been the source of many jokes. He has a quavering, slightly broken voice and a distinctive loud belch (although he sings completely differently, having a beautiful "Irish tenor" type voice), as well as a characteristic wandering eye. He remains friendly and good-natured despite his unfortunate condition. Heavyset, slovenly, and unmarried (though occasionally seen with women), he lives in a very untidy and sparsely-furnished apartment. It has also been implied that he has "lived" in Moe's Tavern.He is occasionally seen doing some sort of menial labor, such as working for his Uncle Al at Barney's Bowl-O-Rama, but has also been the owner of a successful snowplowing business and been employed by NASA as an astronaut. In the episode "A Star Is Burns", Barney states that he is 40 years old and his first name was revealed to be Barnard, although he also appears to be in the same high school class as Homer in flashbacks. When streaking at his high school prom earned him "about a decade's worth of detention", it was hinted that he was either to be held back a year, or had already repeated.When alcohol is not readily available, Barney is seen drinking just about anything, such as turpentine, varnish, rubbing alcohol, and brake fluid.
